Tamils in the US will hold a demonstration in front of the State Department and the White House in Washington on Friday protesting against the "genocide" against their community in Sri Lanka.

'Tamils Against Genocide', a pro-Tamils organisation, will organise a rally and hunger strike to urge US President Barack Obama to bring an end to the "genocide" in northern Sri Lanka, where the Army and LTTE are engaged in a war.

"Tamils have been systematically attacked and brutalised since the government ordered international aid agencies out of the region last September," the group said in a statement.

"Tamil civilians have come under intensive artillery shelling, aerial bombardment and gunfire in the conflict zone in Vanni, with hundreds being killed daily," it said.

Tamil Americans and their friends would descend on Washington to fast in solidarity with Tamils in Sri Lanka, who are experiencing a food crisis according to the World Food Programme, it said.

"The Sri Lankan government has completely refused access to this (northern) region for humanitarian aid, food convoys, medical supplies, journalists and other international observers," the group said.
